Structured and protective mountain running shoe, suitable for endurance runs such as ultra trails and ultra marathons. Akyra is particularly enveloping, comfortable, and flexible, designed for long outings. It features a very enveloping and comfortable upper built on three layers, which provide the following properties from the inside out: comfort thanks to the seamless construction; flexibility and structure due to the innovative MicroLite Skeleton™ applications that dynamically support the foot while running; protection thanks to the structural Flex-Guard™ applications in microfiber, which give the shoe lightness while still providing a barrier against potential wear when brushing against rocks and roots. Extraordinary stability is provided by the TrailCage System™ technology, which lies between the two upper layers and gives the shoe structure and fit by integrating with the lacing system. The sole developed by La Sportiva's R&D, featuring a new shoe profile and FriXion XT compound with Impact Brake System and the exclusive Trail Rocker design, supports the natural foot strike "outer heel – inner toe" while running. Cushioning, protection, and comfort, three aspects with perfect geometry: the origami that inspires the entire design of the footwear. With Akyra, running becomes an art.
